.gitana lllatnt @tina The Schedule referred to in these Letters Patentand making partbf the sans.

To all whom 'Lt 'may concern Be it known that I, THOMAS Onnrsrr, of thecity, county, and State of New York, have invented a new and usefulImprovement on Paper-Satining Machinos; and Ido hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make anduse the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 represents a side elevation of thisimprovemeut.

' Figure 2 is a transverse section ofthe same. Figure 3, a plan or topview of the same.

Similar letters of reference indicate like parts.

This improvement relates to a class of machines used for imparting apolish or iinish to paper, by means of rotary brushes, and commonlyknown as paper-satining machines.

The machine in common use for the purpose, cousists of a large centralrotating drum, of wood or metal, around which the paper passes.Supported in bearings at intervals, around its upper circumference, areplaced several rapidly-revolving brushes, of small diameter, which,being brought to bear upon the paper passing over the central roller,smooth and finish the surface of the same.

My machine effects the operation with greater per- 'eetion and speed,and with the expenditure of less power. I employ but one rotating brush,of large diameter.

F and G represent the framing of my machine, which supports the variousworking-parts thereof.

The paper wound upon the spindle D is passed alternately under and overthe rollers B and G, after which t is lwound up upon the roller D.

rEhe rollers B are of polished metal, and serve to press the paper inits onward movement through the machine, against the rotary brush A,which is put intol rapid motion by means of a belt on pulley, E, or iuany way most convenient.

The rollers B are moved, or held back, by gears a, which receive theirmotion from a small gear-wheel 011 the shaft of brush A. These rollersmove in the same direction as the brush A, but at a less speed, thusretarding the passage of the paper, retaining it longer in contact withthe brush A.

The rollers O are loose in their bearings, and are for the purpose ofraising the paper from the brush A, after passing under the rollers B.

The spindle D', upon which the paper is wound, al@ ter passing throughthe machine, may be revolved by hand, or by means of pulleys and a beltfrom the shaft of brush A, in which latter case the tension of the papermay be regulated as desired by a friction-clutch.

The set-screws f are for the purpose of adjusting the position ofrollers B, thus compensating for the wearing down of the brush Aconsequent upon use. The intermediate gears between the rollers B arealso adj usted by means of the arms B, upon which they are carried. l

\Vhat I claim as my improvement, and desire to secure by Letters Patent,is

The single central revolving brush A, and the series of pressure-rollersB, which may be loose on their axes, or driven by gears or belts fromthe central shaft, and the rollers C, arranged and operatingsubstantially as and for the purposes described.

The above specification of my invention signed by me, this-8th day ofMay, 1868.
